Milling Compass / Fräszirkel Bosch 1200

I created a milling compass for my Bosch 1200 milling machine.

The idea was to create something so i can mill round templates preffy fast and easy.
So i started to CAD something to get that done.

I do own a BOSCH 1200 Milling machine and so i designed something for it.

The final result is open for everyone to use.

Things you need to buy 

2 pice Hexagon Screw M8 DIN 933 with a lenght of 40-50 mm https://www.amazon.de/dp/B0BTJ3W1Q8/
1 pice Hexagon Screw M6 DIN 933 with a lenght of 20 mm https://www.amazon.de/dp/B07RSJLMM2
2 pice star handle nut M8 https://www.amazon.de/dp/B0C7ZLTV86
2 pice 8mm Ø round steel (i used 1000 cm) https://www.amazon.de/dp/B0BS6S82VY
 

Print the Tool:

Load both to your slicer software, flip the TOP part 180 degrees, so the typing is on top.
I printed in 0.20 with PLA, standart infill and no supports.

Assembling the Tool: 
The Bottom part is created, so all Srwes firt kinda tight, so the wont fall out.
If you want, you can glue them inside, but it is not necessary.
Then simpley put the Top part into the scews, the diameter of the hole is bigger, so the top part fits loose and you can easy move it.
Well then just asseble the round steel to your milling machine and the tool.

Use of the tool:
Drill a small 6mm hole into the center of your circle, push the m6 scew into it. Then keep the hadle nuts open, set the mill to the radius, close the nuts and mill whatever you want.

MEASUREMENT of the round steel holes.
My Bosch 1200 uses 84 mm distance and 8mm Ø to fix the round steel.
I dont know what measurement other mills use. but you can use every mill wich supports 8mm Ø fixation.

Additional information:
The holes for attaching the steel rods are designed in such a way that they fit properly
